A Rice Memorial High School student was injured after being allegedly assaulted by another student with a knife on campus during an attempted robbery Thursday morning, according to South Burlington police.

The juvenile victim, 16, whose name is being withheld by police, suffered a minor laceration to his hand, and he was treated at the school, Deputy Chief Shawn Burke said.

The suspect, 17, voluntarily spoke to police after the incident, Burke said. He had left campus after the incident, so no lockdown was triggered.

The investigation is still unfolding so some information, such as how well the students know each other, may change, police said. Preliminary information suggested the two may not have known each other.

South Burlington police and fire departments were called to the school at 7:54 a.m. for the reported assault. Officers later learned the assault was part of an attempted robbery.

Students were held in their first-period classrooms and the school limited movement in the building while police responded and began to investigate the situation, Burke said. Burke, whose oldest son is a student at Rice, said that as a parent, he was pleased with the measures taken by the school in the incident's aftermath.

"I feel the school took all the adequate measures to keep their community safe," Burke said. "I'm very comfortable with how they responded."

Attempts to reach officials at Rice Memorial High School were not immediately successful Thursday.
